Season 2, Episode 4: Bully for You

This brief conversation demonstrates how Catherine is viewed as a "wild child," which is reflected in how she deals with suspected criminals: like a bully. Rather than denying it, she agrees and takes it one step further.

Nick: She was not?
Warrick: She was! I saw her in action
Nick: No! Catherine?
Catherine: I was what?
Warrick: Oh I was just telling Nick how you were a bully in high school!
Catherine: I was but not the kind you wanna take a gun out and shoot.
